Last days one of our websites is being attacked by spambots. The comment forms always have been protected by Mollom's text analyse, but for some reason it looks like these forms are no more protected at all. This might be a side effect of using Boost for some weeks, although the comment forms are set as an exception and headers looks ok ("X-Cached-By" is missing like expected).

I did some tests with "test modus". The website's contact form is protected fine that way, but comment forms are not. When Mollom set to use a captcha, this captcha is showing up on the contact form but not on the comment forms. What am I doing wrong? Any ideas?

Just an update: after debugging for some hours I reinstalled Mollom. At that point it turned out that may API keys were no longer valid - which is very surprising me as they were valid before and "admin/reports/status" nor Mollom settings pages ("admin/config/content/mollom/settings") were warning me. I added the new/other Mollom keys and now everything is going smooth again.
